' This invention relates to improvements in dish washing, it particularly relatin to washing dishes by raising a wall of was ing fluid thereabout by centrifugal force, deiiect.- ing fluid from the wall against the dishes and allowing it to return to the source from which it was raised, and a machine for per-' ratus.

Fig. 4 is a side elevation of the water 1n- `tercepting and directing bucket.

Fig. 5 is atop plan view of one of the buckets and its supporting rod, the rod being. shown in section on .the line 5-5 of Fig. 4.

Fig. 6 .is v'an enlarged side view lo'f one of th buckets and a portion of its supporting ro Fig. 7 is a top plan of a portion of the dish supporting asket.

Referring to the drawings 1 represents the top of a table preferably of rectan lar form and provided with legs 2 whlch ave v their lower portions connected by` spider` shaped supporting member 4. The member 4 has a centrally-arranged vertically-extending bearing support 'provided wlth up r an lower inwardly projecting ann 4o ila es 6 and7. Thismember4 and its cen; traly-arranged support 5 forml the means for supporting. a water container 8 and its mechanism. The container 8 is of a bow sha having the inner surface of ormed on concave lines for a pur tobee lainedandsecuredtotheunersurfaceo vthebottommacentral position is 4a. plate 9 having a downwardly projecting `hollow shaft 10, which pro ects through thecircular'G and bearingsY 11 'are mounted on thev upper ange 6-and serve as a direct thcshaftl anditsplateQwlnle ball 12forthelowcrendofthe Fig. 3 is a vertical section of the appamarsan of the flange 7 and the worm ear 13 secured to the shaft. 'A worm 14 riven from an electric motor 15 meshes with the worm gear 13 for the purpose of rotating the owl; the motor being supported from the spider 4. The worm wheel and worm are enclosed by a casing 16, the lower end ofy which is provided with a threaded nipple 17 to which a hose connection ma be attached for drainage purposes. he con- 55 taner 8 in line with the hollowshaft 10 is provided with a port which is controlled by a valve 18, the stem 19 of which has its lower end .connected with an eccentric pin on a shaft 20 mounted in a bearing 21 in 70 the nipple 17 and provided with a crank arm 22 whereby the valve 18 may be opened or closed. l

The table 1 is provided with a circular opening 23 and to the lower surface of the 75 table is attached an angle-shaped ring 24 which projects inwardly a short distance l from the walls of the opening 23 so as to provide a shelf. The walls of the bowl 8 are extended on curved lines to a point within close proximity to the vertical web of the ring 24 and provided with a bead 25 which more or less closel hugs the ring, and the ring preferably also has an annular sealing ring 24. Supported upon the shelf pro- 85 Vvided by the ring 24 is a second ring 26 provided with a series of downwardly-pro1ect-- ing rods 27 each of which has connected therewith a bucket 28. These rods 27 are of different lengths so thatthe buckets will be 00 arranged in staggered relationas to height,

as shown in Fig.`4. Each bucket is formed with a concave or cup-shaped side 29 as shown in Fig. 5 which is o posed to the direction of rotationof the w1 8. Each 95 of these buckets is rotatably mounted upon certain hmiis andtothis end the hub 30 of the'bucket has a slotted o V31V finto whichv projects a. pin 32, w 'chextends from the rodv27,` the purpose 10o of this beingto Y rmit rotation of the pockets 29'so`that th: buckets may be in or removedfrom the bowl when desired. Thel s i'dc walls of the bowl 8 'are indented at suitablevgintervalscdly to beads bs projectingvet-tiv `exten Torri 33whichactnthewatertopreventitfrom slippingv cause it to rotate withY the in 1151ersul of u ring 2e is` p'govided m rovide inwardly with a depression to form a shelf as indicated at 34 and upon this shelf is hung the dish supporting basket. rIhis basket is formed of wire and consists of an upper horizontally disposed ring 35 which rests upon the shelf 34, 'a second horizontally dis.- posed ring 36, a series of intermediate horizontal rings 36', a series of vertically disposed side arms y37 which are connected to the respective' rings and have their lower ends bentv inwardly in a horizontal direction as indicated at 38, aheavy mesh screen which is connected to the ring 36 and the lower portions of the arms 37 and their horizontal extensions 38, and a screen 40 of finer mesh which is centrally supported on thebottom 'of the screen 39. An annular outwardly and downwardly flaring screen 46, attached to the arms 38, is also provided to prevent food particles from circulating with the water as it is thrown u wardly along' the side of the bowl. For t e purpose of supporting dishes of a flat nature such as lates, saucers and the like, there is provided) in the lower portion of the basket a coiled wire 41, the coils of which are arranged in circular fashion about the basket within the screen 39 and between the coils of which the dishes are inserted. For the purpose of supporting cups, glasses and dishes of such character, there is provided inthe upper portion of the basket a circularly-arranged wire which is so bent as to provide spear-shaped spring clamps, the members of each of which are represented at 42. Each of these clamps 42 projects inwardly and upwardly at an angle as shown in Fig. 8 so that when a cup or other dish of that character is inserted the open side thereof projects downwardly and upwardly in a manner to oppose the direction of motion of cleansing water and to permit the water to readily drain therefrom.

The opening 23 in the top of the supporting table is closed by a removable coverv 43 shown as constructed of sheet metal and reinforced by fa metallic spider 44. This cover has a downturned peripheral flange 45 which rests upon the ring 26.. When not in use as a dish washing apparatus, the table may be utilized for other domestic purposes. Y

The opelaton of the device is as follows: The dishes h ving been inserted. in the basket, the basket is placed -into the container through the opening 23 and the cover 43 replaced, water having been placed-in the container to a suitable height. The motor being started and .the water container thereby rotated centrifugal action causes the waterto flow or creep'up' the side walls of thecontainer, the projecting ribs 33 preventing the \water from slipping and causing it to revolve substantially as fast as the container. The buckets 28 intercept the holder.

water and cause it to be dashed inwardly into the basket and among the dishes. Those .dishes of the container type such as cups, glasses and the like, being supported with their open sides opposed to the direction of the motion of the water and being inclined downwardly, permit water to cireulate freely within the same and drain readily therefrom.

vThe peculiar rounded form of the interior of the bowl, in addition to the 'function stated, also enables the bowl to be vreadily cleaned, this being accomplished by removing the dish basket and the ring carrying the buckets and holding a scrubbing brush or like utensil against the inner walls of the bowl while it isbeing revolved by the motor.

Having thus described my invention, I claim:
